IMPROVEMENT IN PUMPS.

The Schedule referred to-in these Letters Patent and making peri: of thesame.

To all whom it mag/concern Be it known that I, JACOB SCOTT, ofEarlville, county of Delaware, State of Iowa, have invented a new andimproved Pump; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon. l

y Figure 1 is a. central vertical section, partly in elevation, of myimproved pump, showing the position of the parts.

Figure 2 is afront elevation, showing how the exterior poltions of thepump are held in position.

Corresponding letters refer to corresponding parts in each of thefigures.

This invention relates to pumps for elevating water ont of wells, orother reservoirs, andjits 'object is to provide a pump less expensive inits construction, the parts of which are more simple, and easilyconstructed by persons not supplied with ull sets of tools forpump-making, than are the pumps now in use; and to this end,

The invention consists inthe construction and arrangement of the partsof which it is composed, as will be more fully described hereinafter.

A, in the drawings, is a closed box, of any required size, to be placedin or near the bottom of the well,

or other reservoir containing the water to be raised. This box is to beprovided with a series of apertures upon its sides for the admission ofwater to the in'terior thereof.

B represents a short cylinder, which is to be firmly secured to theupper surface of box A. This cylinder may be of any desired shape uponits outer surface, it being intended to use wood generally in itsconstruction. It may, however, be of metal, or of any other material, itbeing provided with an aperture through its centre, within which thepiston is to work. This aperture is to be placed directly over acorresponding aperture in the top of box A, so that adirectcommunication may be' formed between the two.

C represents a valve, which is to be placed at the junction of thecylinder B with the box A, and so arranged that its seat shall be uponthe box A, it opening upward into the aperture in cylinder B. l

1B represents another and a shorter cylinder or tube, which is arrangedvertically by the side of cylinder B, with which it communicates'throughan aperture formed in the side of the latter, at a point, say, threeinches from its bottom or lower end.

Cf represents a valve, which is hinged to, and has its seat upon thecylinder B, it being so arranged as to cover the aperture in its sidewhich. forms the communication. The office of this valve is to preventthe water, after it has been forced out ot cylinder B, bythe downwardmotion of the piston, from returning thereto, as said piston is raisedto allow the' said cylinder to be reiilled withwater.

D represents the aperture above alluded to, which forms thecommunication between the cylinders B and B.

E represents a piston, which fits-the bore-of thel cylinder B, and maybe of any length desired.

El represents a rod, which is to be secured to the piston lil, andextend upward above the top ofthe cylinder for a distance suiicient toenable it to be attached to the operating-handle.

E2 represents the handle by which the piston of the pump is operated,its outer end being attached to4 a bracket, or standard, G, which issecured to the upper end of the cylinder B, as shown in iig. l in thedrawings, or it may be attached t-o a standard at the top of the well,said standard being constructed independently of the cylinder B. To thishandle the rod E1 is attached, at a point directly over the aperture incylinder B, so that as its outer or free end is moved up and down, waterwillvbe forced out of the said cylinder by the piston E, upon itsdownward stroke, the vacuum formed therein by its. upward stroke,whichwill permit the water to dow in through valve G, and refill thesaine, so that the operation may be repeated.

F represents the discharge pipe of the pump, which is to be attached tothe upper end of cylinder B', as shown in tig. 1, it leading from thatpoint to the top of the well, and from thence to any point to which itmay be desired to conduct the water.

At any point above the platform, covering the well or reservoir in whichthe water is contained, this discharge-pipe may be provided with a cap,having upon it the necessary screw for attaching a hose, which willcause the pump, when-operated briskly, to perform the function oi' ahre-engine or a tire-extinguisher,

and thus a safeguard against the destruction ot' buildi ings from thatcause may always be at hand.

H H represent bolts, which are to be secured to the top of box A in anysuitable manner, and extend up and through a cap of iron or othermaterial, to be placed over the top of cylinder B.

Upon the outer upper ends of these bolts, nuts are to be placed, whichwili bear upon .the cap I, and, as they are turned down, will press uponthe cylinder B and box A, and thus unite the parts-together, and preventany leakage at the joints, they havingbeen provided with suitablepacking forthat purpose.

Some of the advantages due to this form of constructionI may be statedas follows:

First, it is more simple, consequently less expensive than any otherpump with which I am acquainted.

Second, it is easily and quickly convertible into an El, lever Ez, :mdfulcrum AGr, all as shown and deengine for extinguishing fires, which isregarded as scribed.

:L very important feature. Signed at Earlville,1owa, this 16th day ofOctober,

Hzwing thus described my invention, A. D. 1869.

What I claim, and desire to secure by Letters Pat,- `JACOB SCOTT. y entof the United States, is-

A pump, consisting of the perforated chamber A, Witnesses: thepump-stock B, eduction-pipe B', hinged valves C 'CUMMINGS SANBORN, andG', eduction-passage D, solid piston E, pisto1i=rod J oHN B. HEALY.
